The first autumn digest introduces useful features that many developers have expected for so long, such as GitHub CLI, as well as some essential notices that engineers should keep in mind for taking the right actions, such as the news about the End of Moment.js support. Also, September turned out to be rich in performance-related articles and the best practices, which are valuable for all of the software development parties.


Moment.js to suspend its work

The development team of Moment.js, one of the most popular date and time library, has officially announced suspension of the development and active work that lasted for nine years.

Starting from September 2020, new features will no more be added to Moment.js, tree-shaking issues will not be discussed anymore, and there will be no significant changes. Thus, the engineers do not recommend Moment.js for the new projects, suggesting Luxon, Date.js, date-fns and js-Jode instead.

GitHub CLI 1.0 is finally available

Recently, the first release of the GitHub CLI 1.0 toolkit has taken place, which provides the ability to manage projects directly from the command line. By leveraging this tool, it is possible to track error messages, create pull requests, display the status of reviews, form issues to releases, and much more.

The tool also involves scripting using the GitHub API. Assemblies are available for Windows, macOS, and Linux (deb, rpm). The code is open under the MIT license.

v3.0.0 One Piece - the major Vue release is here!

The major Vue's development took two years. The codebase was written entirely in TypeScript. The whole framework was split into modules, and any part of the framework can be used in any other framework if desired. Moreover, the framework was developed with three-shaking support in mind. Here is the list of just a few of the updates introduced:

  • support for TS in templates has been added;
  • a new rendering system has been implemented by integrating template compilation into optimized Virtual DOM rendering functions;
  • server-side Rendering has been accelerated;
  • a new composition API has been added to improve the reuse and organization of the component code;
  • in terms of bundle size, performance has been significantly improved compared to Vue 2.

Comparing React and Web components

Matias Huhta builds a simple application using Lit-Element and React and compares these two approaches in three different environments: React, Lit-Element, and HTMLElement (vanilla JS).

In the article, he tells about a simple implementation of a small form, in which a user can insert the desired width and height of a random cat picture and then receive it by querying the PlaceKitten API. He also took care of the starter kit and instructions that are available for everyone interested in this "trick”.

Expanding single-page apps into multiple browser windows

The article introduces the neo.mjs framework, whose main feature is dividing the SPA into related parts that you can work with from different windows/tabs. 

Neo.mjs under the hood makes extensive use of SharedWorker, a special kind of worker that can be accessed from different browser contexts. 

This framework leverages the use of at least three different workers:

  • VDOM Worker (working with Virtual DOM);
  • Shared App Worker (general application state);
  • Shared Data Worker (working with data).


A high-performance blog template for 11ty

Eleventy (11ty) is a static website generator that is actively gaining popularity. Google, Khan Academy, Netlify use it. Malte Ubl, an engineer at Google, recently posted a template for 11ty that has been optimized for building high-performance websites, which allows:

  • generation of different image sizes and their insertion into srcset;
  • extracting the dimensions of the images and using them in the width and height attributes (Cumulative Layout Shift problem overcome);
  • usage of inline CSS and automatic removal of unused styles;
  • fonts preload and lots of other useful things.

Performant front-end architecture of the SPA applications

The DebugBear has published an article with an overview of performance improvement techniques, where they showed a bunch of factors that can slow down the SPA page at different stages of the loading process and described a couple of ways of overcoming performance issues. The majority of recommendations seem to be apparent, but are still great to keep in mind, especially for beginners:

  • avoid sequential render-blocking request chains;
  • skip the network with service workers;
  • consider using server rendering.

How to leverage Content Delivery Networks (CDNs) to improve site performance

CDN (Content Delivery Network) is a geographically distributed network infrastructure that improves website performance using a distributed network of servers. Since CDNs reduce server load, they also lower the costs and can be used for handling traffic bursts.

This article explains how CDNs work, examines image optimization, caching, TLS 1.3, HTTP / 2, HTTP / 3, and much more.

How Goibibo's PWA improved conversions by 60%

Goibibo, India's leading online travel booking portal, shared the insight on how the PWA creation affected the Indian flight business search engines: a detailed overview with the results of implementing specific APIs like Contact Picker or Web OTP.

Core Web Vitals: Wix vs. WordPress, Shopify vs. Shopware... Which is the fastest?

Johannes Boyes published the results of the performance analysis of a large number of sites. The study includes 18 million domains with statistics on the technologies used (CMS, CDN, programming languages, etc.) and data from different devices.

Among the CMSs, Jimdo and Typo3 demonstrated the best performance metrics, while WIX turned out to be the slowest, followed by WordPress. As for the frameworks, Ruby on Rails boasted superior results, while the sites that use Angular turned out to be extremely slow instead. Even though the author puts a special emphasis on the data gathered in the UK, global data here is nor less representative. By no doubt, this is a must-see resource on the topic of performance.


More safe and private browsing experience with Secure DNS

Google officials claim that the Android version of Google Chrome 85 will soon support DNS-over-HTTPS (DoH), which encrypts and secures DNS queries to improve user privacy. In order to get a more insightful look into the specifics of its work and the benefits it offers, it is a great idea to check the article by the link provided below.

An interesting fact - DNS has been around for 35 years, and the implementation of DoH in Chromium has taken two years since there was a risk that a rushed execution could damage services using old DNS behavior. Finally, the feature has been presented, and it is undoubtedly worth trying.

How to ensure REST API security
